Add a codec driver for the Everest ES8316, based on code provided by
David Yang from Everest Semi.
I limited the functionality to items where the vendor code was clear,
and things that can be tested on the Weibu F3C (Intel Cherry Trail).
As a result the initial implementation only supports running in slave
mode at single speed (up to 48kHz sample rate) using I2S. HPD is not
supported.
